George Martin, The Beatles' longtime producer, recalled why he chose not to correct Robin Williams during a recording session, despite noticing imperfections in his performance. Martin's willingness to prioritise personality and character over technical precision reflects his broader approach to producing artists whose value lay in spontaneity rather than polish, a philosophy he applied when working with non-musicians brought in for Beatles-themed projects in the 1990s.

Martin explained that although correcting a vocal take is technically straightforward, he felt Williams's performance, delivered alongside Bobby McFerrin, captured the actor's distinctive energy even if it wasn't the "truest sound" achievable. He compared this to his more conventional studio work with musicians like Jeff Beck, noting that his role shifted depending on the collaborator, sometimes acting as a meticulous arranger, as with The Beatles' 'Eleanor Rigby', and other times simply capturing an authentic moment, as he did with Williams.
